Struct MultilevelDwt 

pub struct MultilevelDwt {
    pub transform: WaveletTransform,
    pub levels: usize,
    pub approx: Vec<f64>,
    pub details: Vec<Vec<f64>>,
}

Multi-level DWT decomposition and perfect reconstruction.

Stores approximation and detail coefficients at every decomposition level, allowing both analysis and synthesis (reconstruction).

Fields

transform: WaveletTransform

Wavelet transform used for all levels.

levels: usize

Number of decomposition levels requested.

approx: Vec<f64>

Approximation coefficients at the coarsest level (approx[0] = coarsest).

details: Vec<Vec<f64>>

Detail coefficients at each level, coarsest first (details[0] = coarsest).

Implementations

impl MultilevelDwt

pub fn decompose(signal: &[f64], levels: usize, family: WaveletFamily) -> Self

Decompose a signal into levels levels using the given wavelet family.

After construction, approx holds the coarsest approximation and details holds detail vectors from coarsest (index 0) to finest.

pub fn reconstruct(&self) -> Vec<f64>

Reconstruct the original signal from stored approximation and details.

Applies inverse DWT from coarsest to finest level.

pub fn total_energy(&self) -> f64

Return the total energy stored in all coefficient vectors.

pub fn level_entropies(&self) -> Vec<f64>

Return entropy at each decomposition level (approximation + details).
